The invention reports on the use of multi-reactive polymerizable surfactants in mixtures of polymerizable mesogenic materials. The polymerizable surfactants are readily polymerized into the liquid crystal film and build a protective topcoat layer. The invention also relates to a method of producing polymeric optical films with improved stability by using the surfactants. Uses of these films are given for various applications including security applications and displays.

A method of doing business in which a Service Provider grants to organizations rights to waypoints to which users may travel and view the organizations' messages. The method may include the steps of granting to the organization the right to the waypoint, receiving from the organization a message to be associated with the waypoint, storing the waypoint and the message in a database, allowing for bi-directional data communication with a mobile device which is able to determine its own location, receiving from the device an indication that the device is at or near the waypoint, and automatically causing the device to display the message when the device is at or near the waypoint.

A silicon carbide transistor used as an ultraviolet light sensor. The light sensor is mounted inside a probe for detecting ultraviolet light generated by combustion inside an engine. The silicon carbide transistor generates a light voltage that is converted to a digital signal. The digital signal is used in a feedback loop for an engine control module for real time engine control in operating environments. The silicon carbide transistor is mounted inside a glow plug sized engine probe mounted in the cylinder head and the probe includes a quartz window allowing ultraviolet light access between the combustion chamber and the silicon carbide transistor so that the silicon carbide transistor can be mounted proximate the combustion chamber but behind the cooling jackets inside the engine head.
